Quantum dot technology to advance molecular cell imaging

Researchers from the University of Illinois at Urbana-Champaign bioengineering team and Mayo Clinic have engineered a new type of molecular probe that can measure and count RNA in cells and tissue without organic dyes. The probe is based on the conventional fluorescence in situ hybridization (FISH) technique, but it relies on compact quantum dots to …

Age-related macular degeneration treated with a stem cell retinal patch

Researchers developed retinal eye patch made from human embryonic stem cells to treat age-related macular degeneration. Researchers grew retinal pigment epithelial cells from stem cells and used synthetic basement membrane to create a retinal patch. Phase 1 clinical trial findings are reported in the journal Nature Biotechnology. Age-related macular degeneration is the most common cause of visual impairment in …
